Three-loop helicity amplitudes of four-lepton scattering in QED
Giulio Crisanti, Thomas Dave, Pierpaolo Mastrolia +3
We present the analytic expressions of the three-loop virtual corrections to the helicity amplitudes of 2 -> 2 four-fermion scattering processes in massless QED. The contributing F…

Higgs-Pair Production via Gluon Fusion: Top-Yukawa- and light-quark-induced electroweak Corrections
Arunima Bhattacharya, Francisco Campanario, Sauro Carlotti +5
Gluon fusion, , is the dominant Higgs-pair production process at the Large Hadron Collider (LHC) and provides the first direct access to the trilinear Higgs self-interact…

LINE: Loop Integrals Numerical Evaluation
Renato Maria Prisco, Jonathan Ronca, Francesco Tramontano
We present methods for the numerical evaluation of the master integrals that appear in the calculation of scattering amplitudes at higher order in perturbative quantum field theory…
